1 dceigu-dhc metallic oxides or mineral colors To all w71 om it may concern:

or inely-divided colored glass is scettered or Be it known that I, THOMAS B. Afr-innenv,

a citizen of the l'nited States, and a resident i of Pittsburg, in the county of Allegheny and Sta-te of Pennsylvania, have invented new' and useful lmproveinents in the Method of rolled over it, v lllanufactnring Ornamental Glass; and l do ter or pulverized glass to adhere to it, after hereby declare the following to be a fnll, which che bulb is reneatcd, so es to fune the clear, and exactdescript-ion of said invenoxides or Colored glass adhering izo it, the tion, reference being had to the accompany@ bulb being then blown in a mold or otherwise ing drawings, and to the letters or figures of i manipulated to forni "he article. reference marked thereon, 1which forni a parl: l In forming articles of glnssware on' which of thisepecication. y l Myi'nviention relates to a new and usef l Il-detern'iined outline ont into the face of the inet-hed of manufacturing ornamental or decl plate or marver A the ornament or" the conorated glass. 1 figuration desired, which may be in. repre lin a highly-heated or Working condition is thus, naming' the colorrngenat- The object of my invention is to provide a sentation of fruit-s, flowers, vines, leaves, simple and inexpensive method of ornament beasts, birds, reptiles, 5cc., 1nd fill seid deine` glass and ela-ss arfielos with letters. figpressed portionsv of the inznver with metallic uros, iiovvers, vines, stripes, and inieoellaneoue oxides, mineral colors, o r nnely-niverm'ed decorations during the operation of forming coloredglass or vitrifiable material. v lnfileed the article, thus shaping and decorating the ofinnkiug the deeign in depression on tile article in colors in one and the same operal inftrvenl may use a plain smooth plate on tion.

M y invention consists in providing the plate or niarvcr with an y suitable design out. therefilled with one or more metallic oxides or mineral colorsor finely-pnlverized colored glass, which will adhere to the het glass bulb and produce a cont-rast of color from the main body, and in finally finishing the article by blowing in a niold or in'any other desirable manner.

Referring;l to the drawings, Figure 1 is n view in perspective of a plate or niaiverliat-- ing the design cnt therein and a bulb of glass on the blowpipe in the act. of being rolled overthe onine. Fig. also a view in perspective of a. plate or inarver having grooves ont therein to form articles with Stripes of diiorent colors t'ronrthe main body ot' the article.'

In carrying ont my invention l embed and fuse into the partially-formed article metallic 1 by means of a rubber block on which the design has been made; or stencil-platee having the desired design cui therein may be need to apply the metallic colors to the inerver,

S0 'as' to be more readily applied, the oil or turpentine being consumed as soon ne it comes in Contact with the hot glass' bulb.

The operator non' gathers on his blow-pipe or purity a bulb of glasn, l, which lie partially expands by blowing, and `then rolle the same over the niarver, While het, from one oid-.e to the other. The coloring-metier in the recesses or cavitiesor on the surface of the :narver adheres to the glass on the blow-pipe, and t-lins transfers the exact design or ornamentation to tiho bull. This bulb of glass non' ref,n heated and blown in a mold or otherwise worked to form the article, when it wilbbe Vfound thai. the. ornani ntal design on the plaie or mahiorwill be produced in contrasting colors on the article. i

lf the article is to be pressed, the relieating oxides or mineral colors, or vfinely divided or pnlverized colored glass, which ivill produce a contrast of color with the inain body when the article is formed.

ln producing mottled glassware-L c., nlassl vvarehoving splotches or spots of different i colors without any regularity as to forni oi l 0f that the thick nnblowirbulb ae it cornes from the pot has sufficient heat io Jinse the colors wit-bont rebeating, und after the bulb has sprinkled on a plain metallic plate omna-r'fer,h and the partially-blown bulb of. while which the design. is printed in inelellie colors said colors being mixed with oil or turpentine the bulb is not required, t'or the reasonwish to place ornameni'e or designs oi n prebeen rolled on' the marvell to take up the colors it isput in the press-mold and severed from lthe blow-pipe and pressed in the'usual manner. y

For fine .decorations orornamentations I prefer to use metallic oxides or mineralcolors, for-'the reason that in the reheating they melt smooth and give a more artistic effect; but good 'effects can be produced by the use of finely-pulverized colored glass, and the colored glass may be used separately or mixed, and metallic oxides or mineral colorsA may also be mixed with th'e powdered glass, so as to produce beautiful effects in tints vand shades of color.

It will be seen that by the above-described method of ornamentation I can readily and cheaply form names, letters, figures, monograms, bands, stripes, and all manner of decorations on the articles while the same are being formed-into the yshape desired, thus dis# pensing with hand-painting and the subsequent firing to fuse the colors on the article, as is nowthe common practice. It will alsobe noticed that Window-glass for churches and for other architectural purposes can be made in the same manner, the cylinders from which the sheet-glass is formed being rolled, While hot, over the marvel' on which the coloringmatteris deposited, after which the cylinder is reheated, split, and flattened in the manner usually practiced in making window-glass.

The method herein describedmay be varied without departing from the spirit of my i'nventiou'f-for example, the design on the plate or marver may be raised or in relief, and the coloring-matter placed on the plain or depressed portions of the marver. This would produce the design in. plain colors, or of the color of the main body of the glass, while the other portions of the article 'would appear in mottled work or in contrasting colors, as the I am aware that it is not new to impress upon the surface of the powdered substances upon which the sheet-glass is .to be placed a suitable design, so that when theglass placid upon it becomes softened by the action of the heat the glass may embed itself into the cavities of the design and soproduce an embossed or raised surface deador bright, as may be desired, and such l do not claim.

Havingrthus described my invention, what I claim is- 1. The herein-described improvement in the art of manufacturing ornamental glass, which consists in rolling the glass bulb or ball, While in a'hot condition'7 on a plate or marver havingthe .designl formed thereon,-on Awhich is placed a vitrifiable coloring material, and

'finally shaping the bulb into the article desired.

2. The herein-described improvement in the artof manufacturing ornamental glass-ware,

which consists in rolling the hot bulb or ballof glass overa marver having a design formed thereon of vitriiable coloring material such as described, thusdepositing the colors on the bulb, reheating the bulb to fuse the colors, and

finally blowing or pressing the bulb in a mold to form the article, as set forth.

In testimony whereof I aiix my signature in presence of two subscribing witnesses.
